The following are in the herbarium of the New York Botanical Garden: Santiago de 
Cuba, Taylor 91; Isle of Pines, Curtiss in 1904; Madruga, Britton & Shafer 721; 
Leggers 5361. 
The three Wright specimens in the Grisebach Herbarium are: Eastern Cuba, 1860, 
no. ‘119=3426;” no. 299 of 1865; and eastern Cuba, 1859, no. 1537. In Sauvalle’ 8 
Flora Cubana the number appears as 3829 instead of 2829. The specimen in the Gray 
Herbarium is numbered 3829. 
4. Sporobolus purpurascens (Sw.) Hamilt. Prod. Fl. Ind. Occ. 5. 1825. 
Agrostis purpurascens Sw. Prod. 25. 1788. 
Vilfa grisebachiana Fourn. Mex. Pl. 2: 98. 1886. 
Sandy pine woods in large tufts, Pinar del Rio, October, Wright 3427a. 
The two Wright specimens in the Grisebach Herbarium are: no. ‘907=3427 from 
western Cuba, 1863, and no. *'885=3427"’, 1863. The type of Swartz’s species is 
at Stockholm; the spikelets are2.5mm.long. Fournier noticed thedifference between 
the two species (S. cubensis and 8. purpurascens) distributed by Wright under 3427, 
but described as new the one already named. Wright 3427a in the Gray Herbarium 
is from ‘‘savannas, Chirigote, July 11.” 
5. Sporobolus virginicus (L.) Kunth, Rev. Gram. 1: 67. 1829. 
Agrostis virginica L. Sp. Pl. 63. 1753. 
Wright 291; Wright 2830 in National Herbarium; Habana, Baker HC 1810, Leon 
284; Mariel, Palmer d&: Riley 736; Isle of Pines, Palmer & Riley 955, 1122; Matanzas, 
Britton & Wilson 151 in Herb. N. Y. Bot. Gard. 
The Grisebach specimen is no. 291 in 1865, ‘‘Seashore, Matanzas, July 8.’’ In 
Sauvalle’s Flora Cubana this ‘is numbered 3830, which is probably correct, as the 
specimen in the Gray Herbarium is also numbered 3830.

55. CHLORIS &w. Prod. 25. 1788. 
Spikelets awnless; spikes dark brown..............-...........- 6. C. petraea. 
Spikelets awned; spikes green or yellow. 
Spikelets distant, diverging; spikes delicate, scarcely I-sided.2. (. cruciata. 
Spikelets contiguous; spikes not delicate, conspicuously 
l-sided. 
«There is some question as to the standing of Capriola as a genus, since it is based 
upon “‘Gramen dactylon offic.”’ (Adans. Fam. 2:31 and 532. 1763.) But since 
Linneus cites under Panicum dactylon ‘‘Gramen dactylon, radice repente, S. offi- 
cinarum Scheuch. Gram. 104’? we may assume that Adanson wished to base his 
genus on this species, though he does not quote a definite author.
